What happened
On April 18, 2026, Iran's IRGC fired upon commercial vessels, re-closing the Strait of Hormuz just hours after its reopening announcement.
The Context
- Internal divisions: The IRGC's military action highlights a rift between hardliners and pragmatic diplomats in Iran, exacerbated by a power vacuum following Supreme Leader Khamenei's death.
- U.S. blockade: A U.S. naval blockade of Iranian ports, initiated on April 13, has intensified tensions and disrupted global energy shipments through this critical chokepoint.
- Economic impact: The closure affects approximately 20 million barrels of oil per day, which is about 20% of global petroleum liquids consumption, leading to increased oil prices.
The Number
— the average daily flow of oil through the Strait of Hormuz before the crisis, underscoring its significance to global energy markets.
Takeaway
Expect continued volatility in oil prices and potential shipping delays as the situation evolves ahead of the ceasefire expiration on April 22.
